.NET: Add bundled Python guest options

[jsturtevant]

Motivation and Context

Adding the bundled package for python to the Codeact provider makes it easier to get started with using python from .net CodeAct provider. The current experience requires you to provide your own image but this makes similar to the Python SDK.

Description

Add HyperlightCodeActProviderOptions.CreateForPython() backed by the Hyperlight Python guest package. Resolve the bundled module through PythonGuestModule.GetModulePath() so the existing backend/module path configuration stays simple and consistent with custom Wasm modules.

Contribution Checklist
